Abstract:

Forty-two pilots were exposed to Gx and Gz acceleration in a variety of profiles and the incidence of arrhythmias investigated. Gz acceleration did not increase the incidence of arrhythmias. Gx acceleration increased the incidence of arrhythmias and this increase seemed related to both the degree and duration of acceleration. Premature contractions, with and without aberrant conduction, from both the atria and ventricles were noted. One subject had paroxysmal auricular tachycardia with Gx acceleration. Possible causal mechanisms are discussed.
